# Calibrate agent

> Define your agent within Calibrate

Define your agent within Calibrate using the config file.

## Configuration

```
You are a helpful customer support assistant for an online store.

You help customers with:
1. Checking order status
2. Processing returns
3. Answering product questions
```

### `tools`

A list of tools available to your agent. See [Tools](/docs/guides/tools) for how to set it up, with examples for different tool types.
